PIPE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 333,618, dated January5, 1886..

Application filed February 4, 1885. Serial No. 154,945. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT C. ELLRIOH, a citizen of the United States,residing at Southington, in the county of Hartford and State ofConnecticut, have invented certain new and useful improvements inCombined Tools, of which the following is a specification, referencebeing had therein to the accompa' nying drawings, in which- Figure l isa view of the frame, and Fig. 2 is a longitudinal section of the sameand of one of the parts in position in the frame. Fig. 3 is across-section of the frame on line a, Fig. 1. Figs. 4 and 5 areperspective views of dies for thread-cutting. Fig. 6 is a perspectiveView of a slide and the cutter. Fig. 7 is a perspective View of a slideand the toothed piece for turning the pipe. Fig. 8 is an end elevationof the slide, and Fig. 9 is a top view of the slide and of one end ofthe handle. Fig. 10 is an elevation of the toothed piece, and Fig. 11 isa reduced view of the handles.

The object of my invention is to make tools, which may be arranged in acommon frame, whereby the functions of pipe-cutters, pipetongs, and diesfor cutting threads on the ends of pipes may be performed as ishereinafter more fully described and explained.

The frame A, Figs. 1 and 2, has the curved head B, and is made in twoparts, B and D, which are pivoted together. The curved head B iscircular on the inside to receive the V- shaped part C, Fig. 2, and thedie L, Fig. 4. In one side of the head B is the stationary pin a, andopposite is the movable pin 1), which has a spring and head foroperating the pin. The pins a and I) hold the part C, Fig. 2, and thedie L, Fig. 4, in place. In the end of the head B is a: threaded hole,a, into which the handle M, Fig. 11, is screwed when the tool is usedfor cutting threads. The part D is pivoted in the part of the frameopposite the head B, and is made in one piece with the pivot m. It isrectangular, and has the rectangular groove F, Fig. 3, in one end toreceive the slides, Figs. 5, 6, and 7, and in the other end the hole andscrew-thread to insert the handle N, Fig. 11. The pivot on has ashoulder which bears on a corresponding shoulder in the hole, and has anut, a9, with a circular base on the end to hold the two parts together.The part D may be turned at any angle with the frame A to allow theslides to be placed in the groove F, and is held in position by the pind, inserted in the frame, and which enters the part D. The pin (1 has aknurled head, by which it is drawn back, and has a spring to force itinto the part D. The part 0 fits into the. head of the frame, and has aV-shaped surface on theinside,against which the pipe comes, and is usedin connection with the cutter I and the toothed part K, Fig. 7.

The die L, Fig. 4, is semicircular, and fits into the curved head of theframe. It has two small holes in its circular surface, one

only of which is shown, into which the pins a and b enter to keep it inplace.

The slide C, Fig. 5. is rectangular, and is made into a die, E, at oneend. The die E and the die L, Fig. 4, are for cutting threads on thepipe. In the other end of this slide two deep slots are made, one atright angles with the other, making the forks g and 9, Figs. 8 and 9.Between the forks the grooved end of the handle N, Fig. 11, is placed,and is the means for moving and retaining the slides. This form of theend of the slide .is common to all the slides.

The slide H, Fig. 6, is slotted in place of the die E in the slide G toreceive the cutter l, which is of the usual form, and turns on a pin, h,in the slide.

The part K, Fig. 10, attached to the slide 0, Fig. 7, has the toothedface i, and is pivoted in the slide 0, so that it is free to turnslightly. The teeth on the face 0' are inclined on one side and cut tothe center of motion on the other side.

The handle N, Fig. 11, screws into the part D of the frame, and isgrooved at one end and has a hand-piece for turning at the other end.The grooved end fits into the forks g on the several slides. (See Fig.9.)

The handle M, Fig. 11, is threaded on one end and screws into the headB.

It is obvious from the above construction that the several parts may bearranged in the frame as desired to perform the functions ofpipe-cutters, pipetongs, and dies for threading pipe.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. The tool-frame comprising the portion A, having the curved head B.and the tool and handle receiving part D, pivoted to the portion A, andthe spring-held 1ocking=pin d for 5 holding said part D fixed withrelation to the portion A, substantially as described.

2. In a tool substantially as described, the combination, with thecurved head B, of the fixed pin a, at one side ofsaid curved head,and

10 a spring-held pin, 1), at the opposite side ofsaid head, for lockinga tool, 0, in said head, as set forth. i

" 3. The portion A, having the curved head ROBERT C. ELLRIOH.
